Cubic Foot/Minute [ft³/min]

Cubic foot per minute [ft³/min] is a unit of volumetric flow rate that measures the volume of fluid or material passing through a system every minute, based on the cubic foot. One cubic foot equals approximately 28.3168 liters. Expressed per minute, ft³/min is widely used in HVAC systems, industrial processes, water distribution, and pneumatic systems where real-time monitoring of moderate to high flow rates is essential. For example, in ventilation systems, an airflow of 500 ft³/min ensures proper circulation and air quality in commercial or industrial buildings. In industrial applications, ft³/min is used to monitor liquid or gas flow through pipelines, ensuring consistent production and process efficiency. It is also applied in water treatment, chemical dosing, and small-scale material handling. Compared to ft³/h, cubic foot per minute provides higher temporal resolution, allowing operators to make immediate adjustments and maintain precise flow control. Using cubic feet per minute enables engineers, technicians, and facility managers to measure, monitor, and optimize volumetric flow, ensuring efficiency, safety, and reliability in industrial, municipal, and building systems.

Day [L/d]

Liter per day (L/d) is a unit of volumetric flow rate that measures the amount of liquid passing through a system over a 24-hour period. One liter equals 1,000 cubic centimeters, so L/d quantifies how many liters of fluid flow or are consumed each day. This unit is widely used in water supply, wastewater management, agriculture, and medical applications to track daily fluid usage or delivery. For example, municipal water authorities often express household or industrial water consumption in L/d to plan supply, treatment, and storage efficiently. In agriculture, irrigation systems are designed based on the daily water requirements of crops, often calculated in liters per day. In healthcare, fluid intake or output for patients, such as intravenous fluids, is also monitored in L/d to ensure proper hydration and medical treatment. Compared to L/h, this unit provides a long-term perspective, suitable for planning and monitoring fluid systems over a full day. Using liters per day allows engineers, planners, and healthcare professionals to manage, optimize, and conserve fluid resources effectively, ensuring sustainability, efficiency, and reliability in both residential, agricultural, and industrial contexts.
